Herb,
I have only seen 12 1906 W+F's in person so far, and none have their magazine bottoms numbered. Mine included (serial # 25929) But 12 is certainly not a significant statistical sample (or as I used to think in college, sadistical sample...) and I am certainly not a seasoned collector.
I did hear from one fellow from Holland (on the SwissRifles board) that is quite knowledgeable and he says they are usually not numbered, but he has seen some; but those may have been done by the pistol's owner so their magazine does not get mixed with with others at shooting clubs and ranges...
See the "hot link" to that posting :

I could not find any mention in Bobba, Datig, or Reinhardt on this issue, either way...
Sorry I cannot be more of a help...
Regards,
Pete... <img border="0" alt="[typing]" title="" src="graemlins/yltype.gif" />
